摘要： A fuel cell power module includes a cylindrical housing encasing a fuel cell stack and an air supply. The housing has a major interior surface. The fuel cell stack can be cylindrical or hexagonal, and comprises fuel cells having an anode and an anode flow field plate, a cathode and a cathode flow field plate, and a membrane electrolyte interposed between the anode and the cathode. The air supply is directed to the plurality of fuel cell cathode flow field plates via a plenum defined by a space between the fuel cell stack and the housing major interior surface. The hexagonal fuel cell stack can be formed by a plurality of fuel cell groups shaped such that when aligned the fuel cell groups together constitute the hexagonal fuel cell stack.

摘要： A fuel cell anode flow field includes at least one flow channel with a cross-sectional area that varies along at least a portion of its length. In some embodiments, the channel width decreases along at least a portion of the channel length according to a natural exponential function. This type of anode flow field can improve performance, reduce fuel consumption and/or reduce detrimental effects such as carbon corrosion and catalyst degradation, thereby improving fuel cell longevity and durability. When operating the fuel cell on either a substantially pure or a dilute fuel stream, this type of anode flow field can provide more uniform current density. These flow channels can be incorporated into reactant flow field plates, fuel cells and fuel cell stacks.

摘要翻译：燃料电池阳极流场包括具有沿其长度的至少一部分变化的横截面面积的至少一个流动通道。在一些实施例中，根据自然指数函数，通道宽度沿通道长度的至少一部分减小。这种类型的阳极流场可以提高性能，降低燃料消耗和/或减少诸如碳腐蚀和催化剂劣化的有害影响，从而改善燃料电池的使用寿命和耐久性。当在基本上纯的或稀的燃料流上操作燃料电池时，这种类型的阳极流场可以提供更均匀的电流密度。这些流动通道可以并入到反应物流场板，燃料电池和燃料电池堆中。
